This invention relates to improvements in cooling systems for motors and more particularly to motors of the internal combustion multi-cylinder type. The aim is to improve upon the present cooling system by introducing means whereby the water may be more readily circulated through the usual water jacket of the motor and the radiator.

This is accomplished by the provision of a narrow by-path between the forward and rearward ends of the water jacket whereby the water in the jacket may in circulation pass through the narrow by-path and thus be cooled besides providing a suction pump in the outlet of the jacket or increasing the circulation of the water in the system and drawing the hot water from the upper interior of the water acket.

The main object of the invention is to provide a cooling system for motors wherein the temperature of the water is maintained low by the introduction of means for rapidly circulating'the same.

Other objects of the invention will become apparent as the invention is better understood from the following specification and claim.

In the drawings:

Figure 1 represents a fragmentary side elevation of a motor equipped with the present invention,

Figure 2 represents a longitudinal hori- Zontal section through the motor showing the means whereby the cool water is drawn from the extreme lower end of radiator and deposited into the extreme rear end of water jacket, or block,

Figure 3 is a perspective view of the pan employed for forming the by-path between the forward and rearward ends of the water jacket.

Referring to the drawing wherein like numerals designate like parts, an engine head A of conventional construction is provided with the usual multiplicity of cylinders B, the space betwen the cylinders and the head forming a compartment through which water mav flow to maintain the cylinders cool.

The type of motor shown in the drawings is known as the Packard straight six and this design of motor is provided with the usual outlet D, one side of the motor'is formed with an opening Qadjacent each end'thereof, and

an elongated shallow pan 3 has its rim formed with a multiplicity of spaced openings 4 through which securing members may be disposed for attaching the pan to the said side of the motor and over the openings'2 to provide a by-path between the forward and rearward ends of the water jacket.

The usual cooling fan E is mounted on the shaft F anc keyed to this shaft is a pulley 5. A suction pump 6 is mounted on the outlet structure D and in communication therewith. The outlet of the pump has a hose 7 coupled thereto and this hose leads to the top of the radiator.

A bracket 8 projects forward of the structure D and supports a bearing 9 through which the pump shaft 10 is journaled. The forward end of the pump shaft is equipped with the pulley 11 geared with the pulley 5 by a belt 12.

ater passing through the inlet G of the water jacket from the pump H enters the compartment C and circulates through the cylinder therein. The water will also circulate through the by-path formed by the pan 3 to be cooled by contact against the thin wall thereof. The water entering the bypath at the forward end of the motor will pass the full length of the by-path before again entering the water jacket. The suction pump 6 will draw the water through the jacket and will greatly relieve the load on the usual pump employed.

The usual pump will serve to force the water to the water jacket while the pump 6 will operate to flush the water from the jacket for delivery back to the radiator where it is cooled before being drawn back into the water jacket again.

This push and pull will efi'ect a rapid circulation of the water through the system.

In the outlet pipe 7, a valve body 13 is pro vided and equipped with a discular or butterfly type of valve element 14 fixed to the shaft 15-and adapted to be rotated by the knob 16, the set screw 17 is adapted to be fed through a threaded opening in the body 13 to bight the shaft 15 to retain the same at a desired position.

It will thus be seen that by setting the valve element 14 in a predetermined position, the circulationof water through the cooling system will be regulated in accordance with the position thereof. n

In cold *Welthl it may gberdesi-re'd toemaintain the water warm and this may be'accomm plished by partly closing the valve 14.

Having thus descflbedmy inventionfwhat is claimed as new is:

A motor cooling system wherein'theinotor is construotedwith the usual water jacket 3 having an inlet and an"outlet,"a narrowb'y- :pass communicating .the forward end. of .1 the watenjacketrwith the rearwardend thereof v and through'whioh water may circulatefrom .thej acket; a punu-plfor forcing water into the 3m) }jacket, and a suction, pump in the outlet of 'the'sfaid jacket for displacing "water from the jacket. 1 v In' testilnonywhereof I aflix my signature. p v IFRED VAN BUSKIRK.
